PLATE-GLASS-WINDOW FRAME.

SPECIFICATION forming part of Letters Patent No. 344,418, dated June 29, 1886.

Application filed January 13, 1886. Serial No. 188,422.

To all whom it may concern:

Be it known that LVALTON DUANE SMITH, a citizen ofthe United States, residing at Prophetstown, in the county of XVhiteside and State of Illinois, have invented a new and useful Improvement in Plate-Glass-XVindow Frames, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to an improvement in plate-glasswindow frames; and it consists in the combination of an outer frame and an illner frame secured in the outer frame and movable therein, the inner frame carrying the glass plate, whereby the crushing force exerted by a building in settling will be prevented from breaking the plate-glass, as will bemore fully set forth hereinafter, and particularly pointed out in the claims.

Figure l is an elevation of a plate-glass-\vindow frame embodying my invention,a portion of the facing being broken away. Fig. 2 is partly a vertical section and partly an edge view of the same.

A represents the inner frame, in which is secured the glass plate or pane B,in the usual way.

Surrounding three sides of the inner frame, A, is an outer frame, 0, a space, D, being left between the said inner and outer frames, as shown. The lower sides of the outer frame are provided with jogs or abutments E, that bear against the lower outer edges of the inner frame, these being the only points at which the inner and outer frames are in contact with each other.

Zpass through the openings h and through the slots F, and thus secure the inner frame in the outer frame, but out of contact therewith. The side face-boards extend nearly but not (No model.)

quite to the bottom of the window-frame, as shown.

Plate-glass windows have been heretofore frequently broken and cracked by the great crushing strain exerted on the window-frames when the walls of the buildings settle, thus entailing heavy losses.

The object of my invention is to preventthis by placing the glass plate in an inner frame, and securing the latter in an outer frame and allowing the outer frame to move either laterally, vertically, or obliquely for a slight dis tance as the walls of the building settle, without exerting any pressure upon the inner frame in which the glass plate is seen red.

In order to give additional freedom ofmovcment to the outer frame without disturbing the inner frame, the side rails of the outer frame are divided into two or more sections by means of oblique cuts m, as shown at Fig. 1. The side face-boards do not extend quite to the lower sides of the outer frame, in order to permit them to move in a vertical or 0blique direction for a slight distance before bending against the window-sill.

I have herein shown the window-frame as rectangular in form; but it will be readily understood that it may be made in any shape desired.

Having thus described my invention, I claim- 1. The combination of the inner frame carrying the glass and the outer frame, a space being left between the inner and outer frames, for the purpose set forth, substantially as dedescribed.

2. The combination of the inner frame carrying the glass, the outer frame surrounding the inner frame and out of contact therewith, except at the abutments or jogs, and the facingboards secured rigidly to one of the frames and movably to the other, whereby the outer frame may be moved slightly under pressure without affecting theinner frame, for the purpose set forth, substantially as described.

3. The combination of the inner frame carrying the glass, and having the slotsF, the outer frame surrounding the inner frame and out of contact therewith, except at the abutments or jogs, the facing-boards secured to the outer frame and covering the inner frame, and

the bolts or rivets passed through the said said means being rigidly secured to one of the boards and through the slots F,'whereby the frames and adjustably attached to the other outer frame may be moved slightly under pressframe, as set forth. ure without affecting the inner frame, for the In testimony that I claim the foregoing as 5 purpose set forth, substantially as described. my own Lhave hereto aflixed my signature in I 5 4.
